RE:Remember this is a high arsenic Deposit.frozengold,
Check your records...the company has stated more than a few times that the deletrious elements were mainly in the deeper mudstone belts. They reckoned they could blend that ore - should they prove up enough to economically mine underground - with ore from Snip (which is cleaner). The open pit does not have the same elements.
But maybe your agenda is to quietly bash away - good luck with that.
